WisdomTree, Inc. was incorporated by its chief executive officer and founder, Jonathan Steinberg, in Delaware as Financial Data Systems, Inc., on September 19, 1985. The company was inactive until October 1988 when it acquired the assets relating to what would become Individual Investor magazine, a monthly personal finance magazine.

In December 1991, it completed an initial public offering and commenced trading on the Nasdaq Stock Market (NASDAQ). In 1993, the company's name was changed to Individual Investor Group, Inc. and throughout the 1990s it was a financial media company that published several magazines, including Individual Investor and Ticker, newsletters, as well as maintaining several online financial related websites. In addition, the company also began developing stock indexes.

In 2002, the company's name was changed to Index Development Partners, Inc., and Jonathan Steinberg, along with Rayne Steinberg and Luciano Siracusano, continued development of the concepts for the company's fundamentally weighted index methodology. While this concept was being developed, the company sought to obtain financing to recapitalize and become an ETF sponsor.
